Subject: [PATCH] mac80211: minstrel: fix tx status processing corner case
|
|
|
|
Some drivers fill the status rate list without setting the rate index after
|
|
the final rate to -1. minstrel_ht already deals with this, but minstrel
|
|
doesn't, which causes it to get stuck at the lowest rate on these drivers.
|
|
|
|
Fix this by checking the count as well.
